Replacement Battery for INSIGNIA Flex 8 Tablet

This Cameron Sino battery replaces the original power cell in the INSIGNIA Flex 8 inch NS-15AT08 and PR-3956155 tablets. It delivers a 3.7 V, 4000 mAh lithium-polymer pack rated at 14.80 Wh. The unit is brand new and built to match OEM specifications for direct compatibility. It is not suitable for other tablet models or larger devices.

Verify Your Tablet Model and Connector

Before ordering, confirm that your device is the INSIGNIA Flex 8 inch with model numbers NS-15AT08 or PR-3956155. Check that the original battery part number matches CS-STA800SL or PR-3956155. Ensure the physical dimensions of 155.90 x 56.35 x 3.70 mm fit the internal battery compartment. This battery will not work with different INSIGNIA models or other brands.

Li-Polymer Chemistry Runs Cool and Light

The lithium-polymer design produces minimal heat during normal charging and discharging cycles. With no moving parts, the battery operates silently inside the sealed tablet chassis. Power draw follows the tablet's own management system, delivering steady current up to the 4000 mAh capacity. The slim 3.70 mm profile helps maintain the device's original thermal envelope.
